Models, Tools and Data

Core models as part of an integrated modeling framework

Community Water Model

Opensource model to examine how future water demand will evolve in response to socioeconomic change and how water availability will change in response to climate. More

Agro-ecological Zones (GAEZ)

Global Agro-Ecological Zoning (GAEZ) provides comprehensive information for rational land use planning and decision making for food security and agricultural development on the basis of an inventory of land and water resources and evaluation of the biophysical limitations and production potentials of land. It follows an environmental approach, providing a standardized framework for the characterization of climate, soil, and terrain conditions for analyzing synergies and trade-offs of alternative uses of agro-resources (land, water, technology) for food and energy production, while preserving environmental quality.

Global Hydro-economic Model

New tool to inform the design of cost-effective and sustainable water policy decisions More

Harmonized World Soil Database (HWSD v 1.21)

First released in July 2008 and last updated in 2013, HWSD is a global soil database established jointly by IIASA and FAO in partnership with ISRIC-World Soil Information, the European Soil Bureau Network and the Institute of Soil Science, Chinese Academy of Sciences. The HWSD is framed within a Geographic Information System (GIS) and contains up-to-date information on world soil resources. More


A model that traces land and water use embodied in production, trade and consumption of agricultural commodities. More

World Food System model (WFS)

The world food system model comprises a series of national and regional agricultural economic models. It provides a framework for analyzing the world food system, viewing national food and agricultural components as embedded in national economies, which in turn interact with each other at the international trade level.
